FRAME AND PROCESS OF MAKING BAKE.

2 Application filed m 24,

Myinvention relates to a processof making ,metallic or semi-metallic perimetric frames, and particularly to a novel joint for attaching the frames members together.

In the forming of frames for pictures, mirrors and thelike, which are adapted to be hung upon the wall of adwelling, the greatest difiiculty is to provide a strong and inexpensive oint for securing the frame members together at the corners of the frame. 7

I It is an object of my invention to provide a new process for securing together the frame members of a perimetric frame by which a strong joint may be inexpensively formed.

It is a further object to provide a novel perimetric frame. which isunusally strong,

attractive in appearance, sanitary in use, and inexpensive to construct.

, Further objects and advantages are made manifest in the following description and the accompanyingdrawing in which: I l V Fig. 1 is a perspective View of a perimetric frame of my invention.

Fig. 2 is a fragmentary detail View of a corner of the frameshown in Fig. 1.

Fig. Sis a perspective View illustrating a completed joint of the frame of my invention. Referrinv specifically to the drawing, Fig.

' 1 shows a frame 10 having upper and lower frame members 11 and- 12 andside frame 2. members 13 and 14. The frame 10 ishere shown as completely manufactured and as having a glass: 16, installed therein The frame members 11, 12, 13 and 14 have a cross section asindicated in Fig. 3. In these members a base portion is formed of wood which is given the shape shown by being run through a stripper. This shape is common to frame'members employed generally in the construction of frames. such as the frame of 1926. Seria1 No. 111,467.

my invention. The wooden base 20 has a.

rearface 21, a perimetric face 22, anda front.

face 23. Therear face 21 is shorter than the base 20 curves inwardly at itslower portion to 10m the lower edge of the face 26.

A sheet metal sheath is formed about the wooden base 20 and has a rear portion 31 which contacts the upper border ofthe rear face 21, a perimetric portion '32 which is bent from the portion 31 to contact the outer face 22, and a front portion 33 which is bent from the portion 32 to contact the face 23, the inner edge of the portion33 being crimped inwardly at 34 toform a retaining lip 35 whichcontacts the lower portion of the face 26. The portion 3lof the metallic sheath 30 has a lip 38 formed at its inner edge which is forced inwardlyinto the wooden base 20. The wooden base. 20 thus covered with the metallic sheath 30 is first formed in long pieces from which frame members of any desired length are cut.

When it is desired to make a frame of rectangular form, as shownin Fig. 1, the frame members 11 and 12 are cut of an equal length,

angle 0f degrees. The frame members 13 andl4arezalso cut of an equal lengthand mitered. on their oppositeends at an angle of 45 degrees. The frame members 11, 12, 13 and 14are now placed together upon a flat table or working bench in the relation which it is desired they be disposed in the completed frame shown in Fig. 1. When thus placed together the mitered faces of adjacent frame members will abut together as shown in Fig. 4. A surface line of juncture 40 will thus be .formed Where adjacent edges of the metallic sheath 30 of adjacent frame members meet. a I

A strip of metal 42 is formed,.as shown in Fig.4, forv the purpose of connecting together the frame members at the corners of.

the frame. The strip 42 has a corner forming portion 43 which is formed in the shape of an angle iron and which is of thesame length as the width of the portion 32 of the, metallic sheath 30. The strip 42 is bent at the upper end of the corner forming portion 43 so as to form a portion 46 which is directed inwardly and downwardly, as shown, so that when the metallic strip 42 is placed over the corner formed by abutting frame members to cover the line of juncture ll), the outer and front portions of the line of juncture 40 are covered by the strip 42. A retaining prong a4 is formed from the loWer endof the corner forming portion d3 of the strip d2. This prong 44 is bent at right angles to the axisof the corner forming portion 43 so as to project over the outer rear corner of the joint and contact the rear face of the portion 31 of the metallic sheath 30. This prong 44 assists in holding the strip 42 in its covering position, as above described. When a strip 42 has thus been placed over each corner formed by adjacent frame members l1, l2, l3 and lt Which are held rigidly in the relative positions which it is desired they are to hold in the finished frame, the corner forming portion &3 of each strip 422 is soldered to the adjacentedges of outer metallic sheath portions 32 which meet on the line of uncture 40. The soldering of corner forming portions 43 of metallic strips 42 to the members 11, 12, 13 and 14, as above described, serves to join these members together into a single frame 10. The frame 10 is now turned over upon the table and the inner tip 47 of the inwardly projecting portion d6 of the metallic strip 42 is bent inwardly and down over the lips by the use of a punch 18, as illustrated in Fig. 6. This secures abutting ends of frame members 11,12, 13 and 14: rigidly together and provides a complete covering for the lines of juncture formed at the juncture of the metallic sheaths 30 at adjacent ends of these members. The frame is now ready for use and a glass 16 maybe mounted in the recess25 or the frame may be used for any desired purpose. However, for the additional strengthening of the frame it is present practice to drive a corrugated staple into the abutting one s of the Wooden bases 20 of adj acent frame members as clearly illustrated in Fig. 7. It is sometimes practice to drive the staples 50 into place before the strips 42 are placed so as to hold the frame members While the stri s are being placed.

While the strip i2 is shown in Fig. 4 as having the corner formed portion 43 already bent and the front portion 47 already curved before the strip 42 is disposed for forming the corner of the frame 10, it is not essential to thus form the strip 42 prior to application.

. It Will thus be seen that the use of such a strip in such a mannerforms a novel process which is of great value in inexpensively forming a semianetallic perimetric frame. Moreover, the frame 10 formed by the process above described is beautiful as Well as sanitary, is of great strength and durability, and is quite inexpensive to manufacture.
